Objective To prepare nanobubbles and analysis its application for enhanced ultrasound imaging of small-cell lung cancer (SCLC). Methods Nanobubbles were prepared using a thin-film hydration-sonication method. MTT assay was used to evaluate the cytotoxicity of the nanobubbles for SCLC H446 cell line. The contrast-enhanced ultrasound (CEUS) of xenografted SCLC tumors in 10 nude mice was performed using nanobubbles and micro-scale microbubbles, and compared with livers. The time-intensity curve (TIC) was obtained using the Gamma variate and the following parameters were calculated, including area under the curve, time to peak, arrival time, peak intensity, and half-peak time. Results Nanobubbles with spherical shape distributed homogeneously, without obvious aggregation, the mean diameters was (392.1 ±48.6) nm and average zeta potential was (-16.8 ±2.9) mV. The MTT results indicated that the nanobubbles had no obvious cytotoxicity toward H446 cell line within the concentrations used for in vivo ultrasound imaging with nanobubbles (5 μg/ml). CEUS with the nanobubbles showed significantly higher peak intensity, and half-peak time [(18.14 ±0.62) s, (141.55 ±8.21) s] in comparison with the micro-scale microbubbles [(14.82 ±0.51) s, (120.43 ±8.73) s] (P= 0.033, 0.040). There was no significant difference in time to arrival, area under the curve and time to peak (all P>0.05). Compared with livers, the nanobubbles in xenografted SCLC tumors showed significantly shorter time to peak, lower peak intensity and area under the curve, and higher half-peak time (all P < 0.05). There was no significant difference in time to arrival (P > 0.05). Conclusion Nanobubbles ultrasound enhanced contrast agent shows good stability and contrast-enhancement effect in vitro, and provides an experimental basis for targeting ultrasound imaging and therapeutics of SCLC.

The rat single-pass intestinal perfusion model was applied to study the effect of CYP3A and P-glycoprotein on the absorption of buagafuran in lumen of rats. Buagafuran concentrations in intestinal perfusate and blood in vena mesenterica collected at different time points after perfusion were determined by GC-MS. Permeability coefficient of buagafuran was calculated by the equation [P(lumen) = -(Q/2pirl)Ln(C(out)/C(in)) and P(blood) = (deltaM(B)/deltat)/(2pirl)]. The effects of troleandomycin (TAO, CYP3A inhibitor), cyclosporin A (CYP3A/p-glycoprotein inhibitor) on the absorption of buagafuran in lumen were observed. After rat single-pass intestinal perfusion, the cumulative amount of buagafuran in mesenteric vein of rat was 73.4, 82.9, and 98.3 pmol x cm(-2) and were increased 3.9, 4.6, and 5.6 fold by addition of inhibitor of P-gp (LSN335984), CYP3A (TAO) or P-gp and CYP3A (CsA), respectively. Moreover, the metabolized fraction of buagafuran was decreased by 12%, 11% and 21% with inhibitors. The results suggested that the poor bioavailability of buagafuran was mostly due to the interplay of P-gp and CYP3A on the absorption, transport and metabolism of buagafuran in intestine of rats.
